I bought a bunch BTC when it was $17000, then bought a bunch when it is $14000...then the price dropped until 2 days ago. I bought a bunch again when it was 6000ish...haha, now the price went up...so, really, when is it a good time to buy? When it dropped for a while and it rose a little bit, then drop again, then buy?
I suggest to a lot of investors of cryptocurrencies especially bitcoin that you buy coins when the price is at a decrease or at a dip. Because not only are you helping the cryptocurrency recover from the losses it had previously received, but it also enables you to purchase coins easier than normal since the price when there's a decrease is significantly lower than the usual.
